Description

Lukkeanordning for beholder med en utløpsstuss. Closure device for container with an outlet nozzle.

Denne oppfinnelse vedrører en lukkeanordning for en beholder med en utløps-stuss som er omgitt av en radialt utad fremspringende vulst, omfattende en av elastisk utvidbart materiale fremstilt omhylling som er skjøvet inn på stussen og en lukkehette som er skjøvet inn utenpå omhyllingen, hvor omhyllingen er utført med en veggdel som er beliggende innenfor stussens åpning og en veggdel som dekker stussens ytterside med ringvulsten. This invention relates to a closing device for a container with an outlet spigot which is surrounded by a radially outwardly projecting bead, comprising a casing made of elastically expandable material which is pushed onto the spigot and a closure cap which is pushed in on the outside of the casing, where the casing is made with a wall part that is situated inside the spigot's opening and a wall part that covers the outer side of the spigot with the ring bead.

Hensikten med oppfinnelsen er å skaf-fe en lukkeanordning av den nevnte art hvis lukkehette er sikret mot utilsiktet av-tagning fra lukkeanordningens omhylling. Anordningen ifølge oppfinnelsen utmerker seg i det vesentlige ved at omhyllingens nedre kant er omgitt av en oppbøyd krave som danner en oppad åpen rille, i hvilken en ringvulst ved lukkehettens nedre kant løsbart fastklemmes ved sneppertvirkning av kravens øvre, innadrettede, frie vegg-' kant. The purpose of the invention is to provide a closing device of the aforementioned type whose closing cap is secured against accidental removal from the closing device's casing. The device according to the invention is essentially distinguished by the fact that the lower edge of the casing is surrounded by an upturned collar which forms an upwardly open groove, in which an annular bead at the lower edge of the closure cap is releasably clamped by the snapping action of the upper, inwardly directed, free wall edge of the collar.

Ifølge et annet trekk ved oppfinnelsen According to another feature of the invention

er omhyllingens toppkant og lukkehettens innad vendende toppflate utstyrt med aksialt rettede i hverandre gripende forhøy-ninger og fordypninger hvis sideflater i omkretsretningen strekker seg på skrå i nevnte retning. the top edge of the casing and the inward-facing top surface of the closure cap are equipped with axially aligned, interlocking elevations and recesses whose side surfaces in the circumferential direction extend obliquely in said direction.

Som følge av sneppertvirkningen av As a result of the snapping effect of

lukkehettens frie nedre kant er hetten full-stendig sikret mot utilsiktet løsning fra omhyllingen. Samtidig har man oppnådd at ringvulsten presser en del av omhyllingens vegg mot beholderens ringvulst og omhyllingen fastholdes tett og sikkert på utløpsstussen. the cap's free lower edge is completely secured against accidental loosening from the casing. At the same time, it has been achieved that the annular bead presses a part of the casing wall against the container's annular bead and the casing is held tightly and securely on the outlet spigot.

Oppfinnelsen skal forklares nærmere ved hjelp av et eksempel under henvisning til tegningen, hvor: Fig. 1 viser et aksialsnitt gjennom ut-løpsstussen av en beholder med den på-monterte lukkeinnretning, og fig. 2 en de-talj av lukkeinnretningen i utfoldet til-stand. The invention will be explained in more detail by means of an example with reference to the drawing, where: Fig. 1 shows an axial section through the outlet of a container with the attached closing device, and Fig. 2 a detail of the closing device in the unfolded state.

Ifølge tegningen er utløpsstussen 1 av en forøvrig på tegningen ikke vist beholder utstyrt med en radialt utover fremspringende ringvulst 2. Inn på utløpsstussen 1 er skjøvet en omhylling av elastisk, utvidbart materiale, f. eks. myk plast, som har en veggdel 4 som ligger i stussens åpning og en veggdel 3 som dekker stussens ytterside. Begge veggdeler ligger tett an mot stussen 1, og veggdelen 3 har en uttagning 5, inne i hvilken ringvulsten 2 ibefinner seg. According to the drawing, the outlet nozzle 1 of a container not otherwise shown in the drawing is equipped with a radially outwardly projecting annular bead 2. A casing of elastic, expandable material is pushed onto the outlet nozzle 1, e.g. soft plastic, which has a wall part 4 which lies in the opening of the spigot and a wall part 3 which covers the outer side of the spigot. Both wall parts lie closely against the spigot 1, and the wall part 3 has a recess 5, inside which the ring bead 2 is contained.

Den nedre ende av omhyllingens veggdel 3 har en oppad åpen rille 6 med en inn-adrettet fri kant 6'. The lower end of the enclosure's wall part 3 has an upwardly open groove 6 with an inwardly directed free edge 6'.

På omlhyllingen, henholdsvis dennes ytre veggdel som dekker stussens ytterside, er skjøvet inn en lukkehette 7, hvis nedre kant har en ringvulst 8 som løsbart kan stikkes inn i rillen 6, idet den fastholdes der av rillens frie kantparti 6'. A closing cap 7, whose lower edge has an annular bead 8 which can be releasably inserted into the groove 6, is pushed into the outer wall part of the outer wall which covers the outer side of the spigot 6, as it is held there by the groove's free edge part 6'.

Lukkehetten 7 har på undersiden et sentralt fremstikkende sylindrisk tapparti 9 som ligger tett an mot omhyllingens veggdel 4 og stikker inn i stussens 1 åpning. Tappen 9 har en brystning 10 som stikker radialt over omhyllingens overside. On the underside, the closing cap 7 has a centrally protruding cylindrical pin part 9 which lies close to the enclosure's wall part 4 and protrudes into the opening 1 of the spigot. The pin 9 has a parapet 10 which projects radially over the upper side of the casing.

Brystningen 10 har flere diametralt innbyrdes motsatt liggende, aksialt rettede fremspring 11 med på skrå i forhold til omkretsretningen forløpende endeflater, hvor fremspringene er adskilt Ved fordypninger 12. The chest 10 has several diametrically opposed, axially directed projections 11 with end surfaces running at an angle in relation to the circumferential direction, where the projections are separated by recesses 12.

Også omhyllingens overside bærer et antall diametralt innbyrdes motsatt liggende, aksialt rettede fremspring 13 med endeflater som strekker seg på skrå til ut-løpsstussens akse i omkretsretningen, og hvor fordypninger 14 strekker seg mellom fremspringene. The upper side of the casing also carries a number of diametrically opposed, axially directed protrusions 13 with end surfaces which extend obliquely to the axis of the outlet spigot in the circumferential direction, and where depressions 14 extend between the protrusions.

Fremspringenes 11 og 13 høyde er di-mensjonert slik at under lukkehettens 7 dreining i forhold til omhyllingen vil fremspringene 13 henholdsvis 11 som i lukke-stilling befinner seg i fordypningene 12 henholdsvis 14, gli på hverandre og derved forskyve lukkehetten så langt i aksialret-ningen at ringvulsten 8 trekkes ut av rillen 6. Hetten 7 kan deretter trekkes av omhyllingen. The height of the protrusions 11 and 13 is dimensioned so that during the rotation of the closure cap 7 in relation to the casing, the protrusions 13 and 11 respectively, which are in the closed position in the recesses 12 and 14 respectively, will slide on each other and thereby displace the closure cap as far in the axial direction that the ring bead 8 is pulled out of the groove 6. The cap 7 can then be pulled from the casing.

Den del av lukkehettens 7 innervegg som ligger tett an mot omhyllingens veggdel 3, bevirker at veggdelens 3 forsenkede parti 5 presses mot ringvulsten 2 slik at omhyllingen holdes fast på stussen 1. The part of the inner wall of the closure cap 7 which lies close to the wall part 3 of the casing causes the recessed part 5 of the wall part 3 to be pressed against the ring bead 2 so that the casing is held firmly on the spigot 1.

Omhyllingen har på oversiden en oppad fremspringende rørstuss 15 med tilspis-set kant som sikrer dryppfri tømming av innholdet i beholderen. On the upper side, the casing has an upwardly projecting pipe spigot 15 with a tapered edge which ensures drip-free emptying of the contents of the container.
